[libvirt] Disabling bootmenu causes boot to skip over cdrom

Hello, I have domain with the following setup: - 1 VirtIO Disk - 1 VirtIO CDROM - 2 IDE CDROMs Now, depending on whether or not I have the bootmenu flag enabled, the boot sequence skips over booting from CDROM entirely (it does work if the bootmenu is enabled). This started happening after I added the VirtIO CDROM. Is this a bug or am I doing something wrong? Thanks, Keno Fischer
